TAN K WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 425,921, dated April 15, 1890.

Application filed December 9, 1889. Serial No. 333,051. (No model.)

To all whom t may concern:

Be it known that I, PETER IVHITE, of St. Louis, Missouri, have made a new and useful Improvement -in Tank Vater Closets, of which the following is a full, clear, and exact description. v

The improvement relates partly to the constructionof the main valve for controlling the delivery ofi the water from the tank and partly to the means for securing an afterwash in the closet-bowl, substantially asl is hereinafter set forth and claimedLai'ded by the annexed drawings, making part of this specification, in which- Figure 1 is a view, partly in vertical section and partly in side elevation, of a watercloset tank and valves constructed according to the principle of the improvement. In this view all the valves are seated. Fig. 2 is a similar View, but showing all the valves unseated and the water standing at a lower level in the tank; Fig. 3, a similar view, but showing the main discharge-valve seatedv and the afterwash and tank-supply Avalves unseated. In the'last twoviews the main discharge-valve, stem, and valve-seat are in section. Fig. et is a detaihbeing a plan of the seat of the two discharge-valves; and Fig. 5, a detail, being a vertical section of that portion of the main discharge-valve having the air-passage, This last view is upon an enlarged scale.

The same letters of reference denote the same parts. v

A represents the tank, and. B the threaded extension to connect with the pipeV through which the water is discharged therefrom to the closet-bowl. This last-named part is not shown, its nature, as well as mode of connecting the tank discharge-pipe therewith, being well understood.

O represents the main valve for controlling the discharge of the water from the tank into the discharge-pipe. This valve is similar to one already in use, saving as it is modified by the improvement under consideration. The valve is hollow to contain air. Its stemc is a tube extending from the bottom of the valve upward, through it and above it to come, when the valve is seated at the proper level. to serve also as an overfiowpipe for the tank. The valve, in the present instance, is adapted to be unseatcd by means of the lever D, pivoted at d, and having the forked end CZ to embrace the valve-stem and coact with the stem-fl ange c', as indicated in the various views.

The valve-seat E is of the usual form to cooperate with the valve C in the usual manner, although the seat is preferably extended laterally at e to form a seat for the afterwashvalve F, and to contain apassage E', leading from the seat of the valve F to communicate with the discharge pipe, substantially as shown.

.G represents-a passage establishing communication between the interior of the valve O and the tubular stem c, and having means, such as the adjustable screw-plug g, for more or less opening and closing the passage--that is, by unscrewing the plug the passage is opened and by screwing the plug inward the passage is closed. The passage G leads through the roof c2 of the valve, and thence into the stem c at a point therein which comes below the level at which the water stands in the tank and stem when the valve is unseated.

H represents the ordinary tank-supply valve, saving as it may be modified to co-op- "erate with the afterwash-valve lever f. The

valve I-I is operated by a ball-lever h. As the water I rises in the tank the lever h acts to seat the valve, and as the water falls in the tank the lever 7L acts to unseat the valve in the customary manner. Suppose the parts to be in the position shown in Fig. 1. The three valves are seated, and the water is neither enteringv nor leaving the tank. Let the main valve c, by means of the lever D, be unseated, as in Fig. 2. The water is discharged from the tank, the ball-lever 72, drops and unseats the valve I-I, and the water flows into the tank, as indicated at 7L. The current of enteringwater encounters the cup-shaped end f of the lever f, and that lever in consequence is upturned on its pivot f2, and the afterwash-valve F thereby unseated. The water is now being discharged through the passage c into the extension B at a point therein below the seat of the valve O, and it continues so to be discharged until the tank has become refilled sufficiently to cause the balllever h to act to seat the valve II and thereby arrest the current of inflowing water from operating to raise the free end of the lever f,

ICO

whicl1,when no longer upliited, as described, drops and seats the valve F. The passage e is smaller than the inlet h2, controlled by the valve H, and hence the Water, after the valve C is seated, gradually rises in the tank until the ball-lever operates to seat the valve H, and as a certain amount of time is consumed in eecting this seating of the valve H after the valve C has 'become seated ample opportunity is provided for the requisite afterwash of the closet-bowl.

When the valve C is unseated, the air within it renders it buoyant, and its reseating is retarded until sufficient air has been discharged from the valve and water admitted thereinto, to cause the valve to sink. In this respect the valve is analogous to others already in use, and the improvement relates to the special means-namely, thepassage G-for discharging the air. In valves previously con structed by me the air has been discharged past a valve arranged directly in the shell of the valve; in another construction the air hasA been discharged through a tube which leads from, the valve `upward to above the highest level of the Water in the tank, and thence downward again to bring the outlet therefrom beneath the level of the Water, and this tube has been used as the valve-stem. The present construction is advantageous, in that it provides an air-passage which can be readily kept free from obstruction, such as might occur in the Water of the tank and find their way into an air-passage leading from the valve, such as the bent tube described, and also an air-passage which can be regulated, and, further, one wholly independent of the lever or other means for unseating the valve.

I claimy 1. The combination, with the supply-valve, the valve-rod thereof and theiloat attached to the end ot' said rod to close the supply' `the main discharge below the main discharge valve-seat, which passage has less capacity t0 discharge water than the supply-valve has tol supply water, Ithe afterWash-valve, and the pivoted lever of lsaidvalve having a cupshaped end f standing-above the discharge opening of the supplyvalve, so that the incomingwater will keep the afterwash-valve open till the supply-valve is closed, substantially as specified.

2. The combination, with the tank having the main valve-seat E and discharge-extension B, the main valve, the tubular valve-stem thereof, and the supply-valve, operated by the lever` h and float on the end thereof, and having the upwardly-bent discharged part or nozzle h', of the extension e, having ,a passage e', leading from the extension B below the valve-seat E to the valve-seat of the after- Wash-valve, the afterwash-valve F, and the valve-lever f, pivoted on the extension e, having the valve F hung upon it and provided with the cup-shaped end f', that stands over the discharge-nozzle 7L of the supplyvalve, the said valve being capable of supplying Water to the tank more rapidly than the afterWash-valve can discharge therefrom, substantially as speciiied.
